The only way to obtain a good opinion of these two PSU's would be to talk to people who have these PSU's installed in their own systems.

Both have been reviewed by JonnyGuru, and he gives the most reliable and best PSU reviews, ever.

Both of them are links, by the way. :p

Sorry if I came across as an idiot (which I did) I've got the flu, and I'm in a pretty bad mood... :\

He likes his 9.5 scores.....

We just advised what we belived to have been better. OC3D actualy has the best privately owned PSU testing equipment pretty much anywhere. And the resident PSU guru Jim really knows his toffee. The best performing PSU's we have tested at this moment in time happen to be Corsairs, closely followed by Enermax. FACT.

If its antec you must have then coolio dude, Im sure it will serve you well.

Jim is God when it comes to PSU's.

JonnyGuru is a member of another Forum I'm a member of, OCN. He's said many times that the Corsair power supplies aren't the best, with the exception of the HX750 and HX850. The HX850 is an amazing power supply, and is based on a newer CWT DSG design, which is better than pretty much all others, except SeaSonic's X-*50 range.

So yeah, the TX series from Corsair are nothing amazing.

Good for Jonny, but has he scientifically tested batches of PSUs on state of the art testing equiptment?
OC3D have, and Subjective < Objective in reviewing performance.

If it has to be Antec then either would be fine, but I'd probably go with the TPQ-850.

Yes, I believe he does. He's renound for being one of, if no the, best in the field...

I believe he works for Ultra now doesn't he and the role of PSU testing has been taken over by someone else (who certainly does seem to know their stuff though)>

Yeah, well last time I checked anyway.

The PSU testing hasn't been done by him alone for some months now, but the site as a whole is still reputable and produces valid results / tests.

Agreed on the HX750/HX850. Both of those units offer great all round performance. They may not be the best in EVERY area, but cumulatively they are without doubt the best I've tested thus far.

However, Seasonic's I'm not too fond of. Yes the X-*50 range also used by PCP&C offer excellent voltage stability, but whenever I test a unit based on that platform I pick up occasional really high ripple spikes that I believe may not have been noticed by other reviewers. Additionally the XFX 850w PSU also based on that platform died twice in my max load tests indicating that OPP isn't doing its job well enough.

PCP&C don't use the X-*50 range, as far as I know. They've not produced a new unit for a while. The Silencer 750W from PCP&C is built by SeaSonic, but it doesn't use the new X-*50 platform. JG done a review on the 650W recently, it's pretty much the best performer, currently. I'd link to the review, but I got kinda told off for that...

The only OEMs that PCP&C have used (As far as I know) are SeaSonic (For the Silencer range) and Win-Tact (For the Turbo-Cool series).

Oh, and yes, the M12D platform suffers from terrible ripple spikes, as you found in your review.
