550W Roundup: Three PSUs at Different Prices
by Martin Kaffei on October 28, 2010 4:00 PM ESTAntec TruePower New TP-550
The Antec TruePower New (who puts "New" in a product name?) takes some cues form the EarthWatts line, as Antec uses no polystyrene for the packaging. You get a power cable, four screws, and a user manual. Instead of a cable bag for the modular cables, Antec provides a plastic jacket. The PSU is RoHS and SLI-ready and comes with an 80 Plus Bronze certification. The cable sleeving is rather cheaply done, but it's better than nothing.
The surface of the TruePower New is very robust. There are quadratic ventilation holes and a small power switch near the power plug. The fan grill does not stick out, and the housing has a length of 15cm.
| Cables and Connectors | ||
| Fixed/Modular | Main | 24-pin 50cm |
| ATX12V/EPS12V | 8-pin 65cm / 4-pin 55cm | |
| PCIe | 6/8-pin 55cm / 6-pin 55cm | |
| Peripheral | 3x PATA 55-85cm / 3x PATA 55-85cm / 3x PATA 50-80cm+ Floppy 15cm | |
| 3x SATA 55-85cm / 3x SATA 55-85cm / 3x SATA 50-80cm | ||
Antec has more cables and connectors than the other contenders. The problem is that you can't plug in all of the harnesses, as two peripheral harnesses will be left over. However, 55cm long PCIe connectors are nice and 50cm for the 24-pin cable is good as well. Already we begin to see the difference between the TP-550 and the lower priced alternatives.
Since Antec is using a Seasonic design, they had the option to use a Sanyo Denki or ADDA fan. This is a mainstream product so they're using an ADDA fan. It's a ball-bearing type fan with seven blades.

Silentpcreview also does high quality PSU reviews, though aimed at a slightly different market (hence the name). They do review performance PSUs though.Mathieu Bourgie - Thursday, October 28, 2010 - link
There's also the EggXpert (NewEgg forums) Tiered Power Supply List that's a good reference (http://www.eggxpert.com/forums/thread/323050.aspx)... as well as *cough* shameless plug *cough* my own article on the subject "Warning: 6 Surefire Ways of Blowing Up Your Computer Due to an Inadequate Power Supply" located here: http://www.hardware-revolution.com/warning-6-suref...Due for an update for the recommendations at the end, rest is still pretty much valid.

The EggXpert list a terrible reference, out of date and full of mistakes.tomoyo - Friday, October 29, 2010 - link
There's an amazing amount of mediocre/crap psus that are in the Tier 2 section, and yet there's also some very good psus that are somehow Tier 4. I'd say a mostly useless list.hybrid2d4x4 - Friday, October 29, 2010 - link
+1 for SilentPCReview's PSU reviews, though I'd say it's not necessarily a niche for audiophiles/noise-reducing obsessive-compulsives as the name may suggest: they only have one page (of 5-7) for acoustics. The rest is a knowledgeable analysis with some of the most detailed electrical testing and thermal torture testing.erple2 - Wednesday, November 3, 2010 - link
The folks at pcper.com are also particularly good at doing proper PSU reviews. They're one of the only ones I know of that do an analysis of cross-loading - ie heavily load one rail and see how it affects the voltage at the other leads (3.3, 5, 12). They're also a group that I've come to rely on for solid PSU reviews. Now if only they'd do more testing ...Phaedrus2129 - Thursday, October 28, 2010 - link
There should have been some comment on the immediately obvious signs that the TechSolo was going to be mediocre. First thing pointed out should have been the "P4PFC" on the label. This indicates that A.) This PSU is actually an ATX12V 1.x era unit, since it's advertising "P4" or "Pentium 4 compatibility", and second having "PFC" after the P4 indicates that this is a platform that doesn't come with PFC as stock, indicating that it's a lower-end unit.Did the TechSolo fail on the primary or secondary side (before or after the transformer)? If it failed on the primary (perhaps the rectifying bridge went nuclear?) then it would be unlikely, though still possible, for it to kill components. If it was a secondary side component that failed then this PSU is a potential time bomb waiting to wipe out your PC.

on September 12th from Newegg ($64.99 with free shipping and $20 MIR), the OCZ Fatal1ty OCZ550FTY doesn't seem like a bad buy to me. But then it's just running an AMD X4, a couple of hard drives, optical drive, and low end video card.slickr - Thursday, October 28, 2010 - link
Good job in this review, though I would like to see more PSU reviews and possibly include A-Power supplies.Beenthere - Thursday, October 28, 2010 - link
There are a lot of posers in the PSU market including some non PSU based companies adding questionable PSUs to the product mix. I'll continue to just buy PC Power and Cooling PSUs which are the gold standard of the PC industry. No guessing required with a PCPC PSU. They perform as advertised and are guaranteed for 5-7 yrs. depending on model.
