[Tom's] Don't Be Surprised When Your Cheap PSU Blows Up - Page 5

post #41 of 75
I don't understand how a market for things like these exist when the corsair/antec 430 watts can be had for around 20 bucks.

I think most buy HEC brand, which is a decent PSU OEM.

Very few companies like Dell/HP/Compaq, use brands like HEC, Seasonic, Sirfa, or Channel Well Tech.

Like Phaedrus and I stated, there's about 4 companies they go to for PSU's with stock designs.

More onto the matter, HEC is a rather lack luster and "D Grade" OEM. They've usually got poor build quality and poor DC Output quality.

I've seen a few HEC units in OEM PCs. Mainly Acer and a handful of HPs. HEC is on the lower end of the reliability scale, so you only really see it in <$300 cheap-o PCs.

Also we forgot FSP, they're a big one too. Seventh largest in terms of units shipped I believe. Delta Electronics is the largest PSU OEM. I forget the other rankings.

SeaSonic was used as for OEMs in the past, you see them in older high-end Pentium 3 and 4/D Dells and a few other brands, but they weren't exactly common. They made the PSUs for the original IBM PCs, along with FSP. But now they've set themselves up as a premium retail/retail OEM brand, so don't cater to Dell et al anymore.

I think the rankings for PSU OEM's (in terms of units shipped) goes a bit like this:

FSPs really the only one forgotten. Though I don't know who they do PSU's for (prebuilt wise)

The PSU manufacturer then makes some prototypes, sends them over, the PC manufacturer tests them in a lab (or has a third party test for them), critiques them, sends them back, repeat a few times, then a test batch is made and tested, then finally they start full scale production. Large PSU makers (like the three listed) usually actually have a set of standard models that can just have the connector count and other details tweaked to meet the needs of any customer, without having to redesign the electronics all the time, though for really large important orders (>1 million units) they may do a custom design anyway to meet the customer's needs exactly at the lowest possible cost.
I havent bought a dell or etc for some time, but my very old hp had a power supply that anyone one here would consider a "cheap brand" (forgot name since it was 6-7 years ago). Guess that was an exception. Failure of the computer was due to the power supply dying, hence the reason why I used the term of "cheap brand".
