350-450W Roundup: 11 Cheap PSUs
by Martin Kaffei on July 3, 2012 1:30 PM ESTFSP Raider 450W 80Plus Bronze
FSP sent a pre-production sample with the name "Raider", a new series for retail market. There's no package or delivery contents so we focus on the internal design and fan. All we know is that this PSU has 80Plus Bronze, a "SATA Array Cable Design" and a standard case with those unattractive ventilation holes at top. In addition FSP offers a 5 year warranty.
FSP uses a 120mm fan from Yate Loon with a sleeve bearing. The product number is D14SM-12 and it takes 0.30A. A FDB fan would be better but the price could be a problem and Protechnic is still a reason to buy the more expensive Aurum series. FSP differentiates between the two lines by modifications such as this, which helps them reach lower cost markets.

| 1x SATA, 3x HDD, 1x FDD (ca. 55, 70, 85, 100, 115cm) fixed | ||
The internal design looks like a cheaper version of the Aurum series. This time FSP used a Taiwanese manufacturer for all those caps inside. In addition the PCB material is different. However, this is still the active-clamp forward converter we already know, with all advantages and disadvantages given by the design. EMI filtering consists of three chokes, two X-caps and four Y-caps. Both heatsinks are very thin as the components won't heat up too much.

I bought a FSP Aurum 400W 80 Plus Gold about a year ago, and I'm EXTREMELY pleased with it. It's very cool and energy efficientI have my computer on pretty much 24/7, but last week I turned it off for pretty much the first time since I got the PSU to install more RAM, and the PSU was still very cool, didn't feel like it was on at all.

This power supply has been on sale for under $20 after rebates a few times over the last months - it's on sale right now for another day, at newegg 15% off code and rebate.It's a re-badged Seasonic S12II - high quality unit. I got a few as spares, use a HCG-620 myself.

I've got a Shuttle SZ77R5 with a 500W PSU, running an i7-3770k and a GeForce GTX 670... It doesn't get all that much faster than this without your cost/performance ratio going to crap, and the 500W PSU is way more than enough.Why this is the case should be obvious: the processor has a 77W TDP, the graphics chip has a tdp of 170W, which is 247W at full load, and those are the two biggest power draws in the case. Yes, the other parts use power, like the hard disks (I've got SSDs), fans, memory, chipset, etc. but not enough to max out even a 500W PSU.

For your system a 500W supply sounds great, but for other people they might have more stuff in their box that needs more power. For example, my main system has an i7-920, GTX 560, and 14hdds. It was giving me random fits occasionally when rebooting on my old 650W supply (can't remember the name but I believe it was one of the recommended ones either on here or tom's or someplace) I ended up replacing it with an 850W and now I don't get restart cycles anymore. Theoretically, the 650W supply had enough power to run everything (and still 100+W of spare capacity), but something wasn't happy and a large supply seems to have fixed everything.Finally - Tuesday, July 3, 2012 - link
Bullshit.What you are describing is the American mentality towards the environment, not much else.

I think he's almost certainly correct in that the PSU was a problem -- HDDs tend to draw power differently than GPUs and CPUs (same voltage, different rails). The real question is what he's doing with 14 HDDs in a single system. Sounds more like something for a file server, and if you're running a file server you should probably also have a higher quality PSU to begin with.As for your contention that he has an "American mentality towards the environment", kindly take your stereotyping elsewhere. Very likely this has nothing at all to do with his nationality and is simply a reflection of his enthusiasm for computers and technology.

Hard drives are commonly designed to draw up to 2 amps on the 12 volt line when spinning up, so if you spin up 14 hard drives at ones the power draw could be 2A * 12V * 14 = 672 watts. Normally, systems with large numbers of hard drives are configured to spin up a few drives at a time to avoid overloading the power supply. The alternative is to do what you did: buy a very large power supply.JimmiG - Tuesday, July 3, 2012 - link
Still running a Corsair 450W VX PSU since 2007 here. Currently with an overclocked Phenom II X4 system and GTX460. Rock solid. I always laugh when people ask whether their new 750W PSU's will be enough for a Sandy Bridge and Radeon 6850 plus one SSD...bwave - Tuesday, July 3, 2012 - link
Why would you consider any of these when you can get a Cooler Master Elite 460W for $29.99 or a Cooler Master 500w for $37.99 ?I've used hundreds of the Cooler Masters with zero failures, very high quality and it's a name brand!

That's what I want to know. I use the same two all the time, but I am almost scared to find out how they actually test.Most users do not notice, and do not care. They only want the cheapest PSU. I may get them to allow me to installed a better one, but only so far. Most of the PSU's reviewed here are marginal in that regard.
We're talking about systems with a core i3 and integrated graphics, and a single hard drive. Maybe it can push 100-120 watts, when the grand kids try to play WOW on their grandparents' computer. Sometimes they want the $25 model even.
Shoot, for office workstations I use these Cooler Masters even. I haven't had a problem yet. Nowadays that means Core-i5, 8GB DDR3, and 60GB SSD. I built a server recently that only used 18watts at idle! It is just hard to find good PSU's at less then 400 watts.
