Is JeanTech PSU any good

Jonnibravo · 10 Sep 2014 at 17:18

Just bought a r9 290 and I've been offered a jeantech 750w modular psu to replace my coolermaster 650w which is getting a bit old.

I always remember from the early days of pc building people saying never buy a psu from a rubbish manufacturer, TBH I've never heard of this make anyone vouch for its quality?

No.

Terrible.

Rubbish.

Nasty.

Horrific.

Gutless wonder.

Should stick with the coolermaster then.

There will be a label on the side of the units. Look at the Amps on the 12v rails.

Bet the jeantech is weak

CM PSUs are not that great either. Still miles ahead of that junk mentioned in OP though.

TBH I've had my coolermaster since circa 2008 and it has seen several different builds, amazingly it's the only original part from my migration from the old ddr2 boards back in 2008 and its still going strong, guess Ive been lucky.

The Seasonic made 'V series' ones are very good.

And then ignore that label, because the Chinese manufacturer probably just made it up.

Saw a "500w" PSU once that apparently had 25A on the 12V. Hilarious. It had blown up powering a Pentium 4 bare basic machine. Shame about the motherboard.

Made me laugh but so true.

Only good use is a paper weight! even then it would probably fail.

They are a complete joke and could be classed as an IED

This made me think of hiper 520w psu's

Spend £40 and get a Superflower! You'll not regret it!

I bought a CM Silent Pro 600W modular PSU from OcUK in December 2009. It originally powered an AMD Phenom II 955BE/ATi 5770 build, and is currently powering an Ivybridge i5 3350P/nVidia 650Ti setup. Been perfectly reliable, though I do concede that neither build has exactly stretched the limits of the power output.

It really depends who the OEM is. Corsair for example need to STOP using CWT designs stretched to meet the boilerplate rating in their low end CX models.

ok, so? I haven't said it's complete garbage. What I said and meant is that there are better units at same prices.

When thinking of top tier PSUs, you certainly don't think of CM first.

Wrong.

I bought my Cooler Master 850W back in November 2007 and it's still going strong.

I know of a Jeantech PSU that's been running since 2006, it's still bad.

My view, in the case of a Jeantech PSU, make sure the rest of the PC is worth less than the PSU.

In a way your probably right it fail as a paper weight, going back to years gone by before there was proper PSU testing the best way of knowing if your PSU was any good was weather it was heavy or not.

As for Jeantech PSU's..............well there sold by the purple shirter's shop in a retail park near you that should tell you all you need know about this brand.
