£900 PSU
- Thread starter peahead
- Start date
Internals look nice, but worth £900. No chance, they may be the best you can get the the difference between this is something that costs £250 is tiny, it just for people that buy Leica and Apple. 
Lets compare against a decent competitor product.
Seasonic Prime Platinum 1200W https://www.overclockers.co.uk/seas...-platinum-modular-power-supply-ca-05k-ss.html
£244.99
Size, it's massive 150 mm vs 224 mm, it needs to be a lot better to justify using this extra space. Most people would prefer to save the space.
The air vents look more restricted on the MIJ, but both unit are so efficient it's not a major issue.
Cables don't look different to any other high end PSU. I would have expected something better there.
Fans pretty similar in spec, both replaceable. Hard to say which is better. The review didn't go much into these.
Warrantee 12 Y (Seasonic) 10 Y CM.
Internals MIJ win here, that £900 had to go somewhere. But what real difference does it make. Both units have used high end, high rated caps.
Seasonics primary caps total 1150uF, MIJ 1450uF. Both are higher than they could be to do the job.
DC Load regulation both are impeccable, the difference this microscopicly tiny. Seasonic edges the +5, MIJ +12, rest about even.
MIJ wins on ripple, again difference is tiny. Maybe the only people that could possibly get benefit from this are world class overclockers like 8Pack looking
for that bit extra?
Efficiency MIJ wins here averaging around 2% better, 2.5% at max load, but you shouldn't really be running it at that for long periods.
Noise Seasonic wins up to 800 W loads, only at a 1000W does the MIJ take over. Both are so close for the most part you wouldn't know the difference.
Temps pretty much the same within 1c at 650W, Seasonic is slightly higher above this but these are exhaust readings so the cooling is doing it's job.
Maximum load 1345 W Seasonic vs 1435 W MIJ. Both over spec.
Price £245 vs £900 Seaonic wins here.
So MIJ for multi millionaires that like to **** away money and 8Pack. (Which is good cause there aren't many to go round)
Seasonic for everyone else.

Honestly, we saw the reports and the Prime platform is actually better overall, hence why we aren't stocking it.

For a handmade, one-off psu, it's definitely interesting. But not worth the 900 quid. Unless you're the kind of person that simply has to have something that no one else has. But in the case of custom PC enthusiasts, that seems unlikely.
I dunno, someone at ocuk gave the go ahead on stocking those train shaped pc cases too

At least they sold... eventually
