It's clear that some PSUs should never see retail shelves in Europe. The Codegen P-Case 460W belongs in this classification if you want a 460W PSU. In fact, the Codegen is a ~230 watts power supply without power factor correction--not to mention the fact that the efficiency is always below 74%. If you just need a cheap power supply that will function at loads under 250W, perhaps budget products will fit the bill, but we'd suggest looking elsewhere as long-term power costs (and the risk of damaged components) makes this a gamble at best. In our case, the PSU died at 50% load.

Codegen offers nothing more than a few short cables and no PCIe connector. Moreover a cable sleeving would be a nice extra, but we'd like to see better electronics first. Overall the PSU provides two SATA and two HDD connectors on two 20 AWG cables. Additionally, you get a 4-pin CPU connector and a 30cm long 24-pin cable. With 45-60cm the peripheral cables are short too.

Internally, the PSU has a single-layer main PCB. Codegen only uses cheap capacitors and the main caps are common types with only average endurance at 105°C. Most components are undersized. Transient filtering is inadequate and there's no MOV (as an AC overvoltage protection). The SD6109 IC has some important safety functions including OVP and SCP but this is not enough since OCP is missing. +5V and +12V are connected to the same controlling and share one output choke which gone into saturation during our test. Overall, the component selection and build quality make this a low-end offering.

+12V is always higher than 12.31V (12.60V is the ATX limit) while the other rails are lower. The voltage regulation is bad--even for such an affordable product. While efficiency is only 73% at high load, the ripple results could have been worse. The power factor is very low on 230VAC since there is neither a PFC choke nor an active PFC circuit. Another disadvantage is the high fan RPMs at 50% load. The PSU is relatively silent from 5 to 10% load and still quiet at 20%. However, it does get too loud at higher loads--nothing unusual for a PSU like this, but you'll want to ensure your PC doesn't reach high loads if white noise bothers you (and that your PC won't die).

In summary, the Codegen P-Case 460 from Q3335-A2 bundle is one of the worst PSUs we have seen so far. It doesn't have any special features beyond an acceptable noise level (at low load). We can hardly recommend a 460W PSU with 230W real power and no power factor correction. In addition the PSU died during our test. The whole bundle costs about 30 EUR in Europe.

You get what you pay for!

    Not too often we see a review on a low-end PSU. Thanks for reviewing this one; it's an eye opener.
  • damianrobertjones - Friday, April 27, 2012 - link

    I love this review :)

    Now all we need is honest, down to earth reviews of:
    - Apple kit
    - Netgear products
    - Android operating system

    Thanks for reviewing a low-end PSU. It's rare to find any reviews at this price-range. Seems €30 is too high a price though considering you can buy a Corsair VX430 for under €40.

    Would be nice to see some more budget PSUs reviewed - maybe there's even one which can actually delivery its rated output.
  • Iger - Friday, April 27, 2012 - link

    To be fair - it's €30 with the case!

    How is there anything fair about selling junk, at any price?

    Codegen products are normally sold in markets with poor and expensive oferings:

    Here in Argentina a Codegen 500 PSU can be found by us$22.
    The cheapest brand name alternative would be a CoolerMaster 460W eXtreme Plus RS-460-PCAR, the lowest in Coolermaster portfolio, at us$75.

    The minimum PSU recommended for the for a Gamer configuration would be the Antec Vp450 at us$89

    Considering that other PC componentes are also a lot more expensive than in USA, and that average income is 5 times lower, what PSU would you use for running a basic configuration for Internet browsing, Outlook and Word?

    The review itself says you could probably get away with this PSU if you used it in a lower power demand situation. A budget CPU w/ integrated or budget graphics probably would not stress this PSU. Though you can't trust that the Codgen 500W available in your market has the same components as the 460W in this review.

    I found a decent cheap PSU that seems to work well. I used it for a month on my main gaming rig, with an unlocked and overclocked Phenom @ 3.6 Ghz, and an HD6850.

    it's fairly quiet and seems to be able to supply decent power. I currently use a Corsair HX650, but this cheap one seems to due well for a basic gaming machine.

    If you aren't using it anymore, you might think about contacting Anandtech to see if they will do a review on it.

    Maybe you dodged a bullet, maybe not.
