Antec snubblar med High Current Gamer

Som ett led i god nätaggregatsupplysning tänkte jag bara visa senaste exemplet på hur en tillverkare (Antec i detta fallet) först kan släppa ett av de bästa nätaggen någonsin, High Current Pro 1200W

"Prior to today's launch of the Antec High Current Pro 1200W (HCP-1200), the Corsair AX1200 ruled the roost as the best 1200W unit on the market. After taking in to account the excellent build quality, the outstanding voltage regulation, outstanding efficiency, and outstanding DC Output Quality results we begin to see a pattern where the HCP-1200 edges out the AX1200 on just about every front. Even when it comes down the Transient Load Testing, which has tripped up many high quality units, we see the HCP-1200 coming up as clearly the best 1200W unit we have seen to date.

Clearly, with the Antec High Current Pro 1200W (HCP-1200) coming in at the same $299 as the recent Corsair AX1200 we have to tip our hat to the new king of the 1200 watt PSUs as Antec has really hit this one out of the park with the HCP-1200 surpassing the AX1200 in almost every way."

För att sedan lansera en modell med snarlikt namn, som är katastrofalt mycket sämre och slutade fungera två gånger i rad vid fullast: High Current Gamer 900W

"Perhaps the most disappointing thing here is this unit looks so very good from every aspect before we actually tested it, that when it fails it leaves feeling like, "Really?" The HCG-900 isn’t the first time we have been disappointed by a unit from a brand that normally is a solid recommendation, and it certainly won’t be the last, however the very nature of this unit's failure and the other assorted weak points of this unit make it something that seems strangely out of place in its current position in Antec’s lineup particularly on the heels of the excellent HCP-1200. Some days you win, and some days you lose. Today seems to just be one of those days that Antec lost with the HCG-900.

And to again point out, we had very similar experiences with not one, but two Antec-supplied units. Whenever we have a failure we request a second sample to verify our results, and in this case, both Antec units showed to have the same failure pattern.

The Antec HCG-900 has a lot of things to like going for it including what looked to be an excellent build quality, however at the end of the day the unit simply was not an excellent 900W unit as billed, but rather a decent 700W-ish unit. In addition to the failure to meet its full advertised output in our test environment, the HCG-900 was also a bit hamstrung by poor Transient Load Tests results and perhaps some poor quality control on the part of its connectors as the voltage regulation on the motherboard connector was significantly worse than on any other unless the unit was assisted during the testing. The Antec HCG-900 currently costs $145.00 it doesn’t even make much sense as a 750W power supply when the EA 750 outperforms it at $99.99."

Med detta vill jag än en gång visa och varna för att man aldrig generellt kan säga att ett visst märke alltid är bra. Varje enskild modell måste kontrolleras innan köp. Tråkigt men nödvändigt på dagens marknad. Båda ovanstående modeller är tillverkade av Delta, men olika plattformar.

De testade olika. HardOCP maxade 12V samtidigt med max total uteffekt (70/6/4/2/0,5 A totalt för respektive spänning 12/5/3,3/5vsb/-12), vilket Jonnyguru inte gjorde (68/8/8 A enbart). Den skillnaden kan räcka, men agget måste ju klara angivna effekter oavsett.
Jonnyguru maxade 12V vid crossloadtesten, men då belastade de enbart 1A på 5 och 3,3V och därmed nådde de enbart 863W, vilket är en bit från max vad agget ska klara.

When attempting Test #4 the Antec HCG-900 repeatedly turned off at anywhere from ~1 minute to ~3 minutes 12 seconds into the test until finally, with the second sample, not only did it switch off it would not longer restart. Yes, we did test two Antec units with the same failing result. Both samples were acquired directly from Antec PR.

It is just not configured appropriately for the thermal envelope. Antec had raised the OTP point on it supposedly by the second sample and that one did worse than the first.

Jag hävdar fortfarande att ett nätagg som inte klarar av full last vid realistiska temperaturer (hur många har sina agg löst hängande utanför lådan?) ska undvikas. Men Sweclockers testar ju i friluft och många knäböjer ju framför det altaret ändå.

Men, ok, bara för att höja mungiporna på mina forumvänner ändrar jag och skriver "slutade fungera" istället. Alla glada?

Har du numret?
